Abstract (en)
A compact, easy to manufacture quarter-wavelength microstrip element especially suited for use as a mobile radio antenna has performance which is equal to or better than conventional quarter wavelength whip-type mobile radio antennas. The antenna is not visible to a passerby observer when installed, since it is literally part of the vehicle. The microstrip radiating element (64) is conformal to a passenger vehicle, and may, for example, be mounted under a plastic roof (56) between the roof and the headliner (58).
